BACKGROUND OF THE INVENTION Field of the Invention

This application generally relates to a virtual reality simulator, and in particular, magazine simulators for guns that provide an interface with virtual reality systems.

Description of the Related Art

It has long been desired to provide personnel training to improve their skills in aiming and firing shotguns, rifles, handguns, and other weapons. Law enforcement and military training often place trainees into situations that require quick visual and mental assessment of the situation as well as an appropriate response with a weapon. Trainees are often subjected to adverse situations to test their abilities to effectively react.

Traditional training methods in marksmanship and firing tactics for hunters and other sportsmen, police, military personnel, and others, leave much to be desired from the aspects of realism, cost and practicality. Many firing ranges have limited capacity. Moreover, most existing firing ranges do not provide protection for the shooter against the natural elements such as rain or snow. Because of the noise levels normally associated with firing ranges, they are typically located in remote areas requiring people to have to drive to remote locations. The ammunition, targets and use costs for the range, make such training expensive. Furthermore, when live ammunition is used, expense, risks, administrative problems, safety concerns, and government rules and regulations are more burdensome. For training in marksmanship and tactics, it is beneficial to have an indoor range where shooters can fire simulated projectiles against simulated moving targets.

Video games are increasingly more realistic where users may be placed into immersive virtual environments. First-person-view shooting games offer players the ability to perform actions such as walking, crouching, shooting, etc., using a mouse and keyboard. However, these games are usually played in front of a computer where the user is sitting in a chair and are adequate for personnel training. Virtual reality systems may improve gaming experience where the player's movement in the game is dependent on their actions in physical space which makes the game more immersive than a traditional video game. Despite the realism provided by virtual reality systems, players are often provided with game controllers that are either tethered or have the look and feel of toys. As such, existing virtual reality game controllers that are representative guns differ from actual guns in feel and balance, and thus reduces the effectiveness of the training for real life.

There is thus a need to provide an improved shooting simulator and process.

Safety component 406 may be correlated with on and off positions of a safety 410. Operation of the safety 410 may cause safety component 406 to transmits a signal to switch 110 that indicates the position of the safety 410 (e.g., either on or off). Trigger component 402 may be coupled to a trigger 408 of the electronic control weapon 400 such that when the trigger is pulled, trigger component 402 may communicate a signal to switch 108′ that indicates the trigger 408 has been pulled. Switch 108′ may relay signals from trigger component 402 and switch 110 may relay signals from safety component 406 to the tracker interface 104′ illustrated in FIG. 5 . Electronic control weapon 400 may further include a weight 112 that provides a weight and feel of a realistic (e.g., electronic) weapon.

FIG. 5 presents a bottom view of a tracker interface according to another embodiment of the present invention. Box magazine 102′ may be assembled or attached to tracker interface 104′. Tracker interface 104′ includes pin pad 502, screwing bolt 504, and stabilizing pin 506. In this exemplary embodiment, pin pad 502 includes three pins, e.g., a first pin may correspond to a trigger pull signal, a second pin may correspond to a safety position, and a third pin may correspond to a ground connection. Pin pad 502 may include pins corresponding to given signals from switches 108′ and 110 of box magazine 102′.

Signals from switches 108, 108′, or 110 may be transmitted to tracker interfaces 104, 104′, respectively, and activate corresponding electrical switches to pin pads 302 and 502. Articulations from gun 200 or electronic control weapon 400 that are communicated to any ones of switches 108, 108′, or 110 are not limited to trigger pulls and safety positions and may include other actions, events or signals that may be generated from weapons. Pin pad 302 and 502 may provide an electrical connection interface with tracker 106.

FIG. 6 presents a tracker according to an embodiment of the present invention. Tracker 106 may comprise hardware configured to track and link actions, events or signals from gun 200 or electronic control weapon 400 to a virtual reality computing device. Tracker interfaces 104, 104′ may be attached to tracker 106 to facilitate communications between gun 200 or electronic control weapon 400 wirelessly to the virtual reality computing device. According to one embodiment, the virtual reality computing device may comprise a server running a Unity engine (Unity Technologies) that is interface with a tracker 106 that includes hardware, software, and software development tools from virtual reality providers such as VIVE™.

Signals from pin pads 302 and 502 on tracker interfaces 104 and 104′ may be convey to tracker 106 via pogo pin connector 602. Pogo pin connector 602 may comprise a plurality of spring-loaded pins that support electrical connection with pins on pin pads 302, 502. Signals from the pins on pin pads 302, 502 may be mapped into commands based on contact connections with corresponding pins on pogo pin connector 602. The commands generated on tracker 106 may be received and interpreted by the virtual reality computing device.

Tracker interfaces 104 and 104′ may be mated with tracker 106 by inserting stabilizing pin 306 and 506, respectively, into a stabilizing pin recess (not illustrated) of tracker 106. The stabilizing pins 306, 506 provide proper alignment and contact between pin pads 302, 502 and pogo pin connector 602. Tracker 106 may further include image sensors and/or non-optical sensors (e.g., utilizing sound waves or magnetic fields) that can be installed in hardware to track the movement of a user's body. According to another embodiment, optical markers may be placed on tracker 106 (or alternatively on magazines 102, 102′, or tracker interfaces 104, 104′) for motion tracking using cameras to track movement of a user.

Tracker interfaces 104, 104′ may be secured to tracker 106 by securing screwing bolts 304, 504 to mount 604. Screwing bolts 304, 504 may be tightened and loosened from mount 604 via a thumbwheel 114 as illustrated in FIG. 7 . FIG. 7 illustrates a front handle view of a gun loaded with a magazine assembly according to an embodiment of the present invention. The thumbwheel may be tightened until the tracker interface (104, 104′) is securely fixed in place with tracker 106. As such, an assembly of box magazine 102, 102′, tracker interface 104, 104, and tracker 106 provides a magazine simulator 100 provides a virtual reality controller device that can be holstered and unholstered, useful in simulating real training.

FIG. 8 presents a repeating mechanism according to an embodiment of the present invention. Certain guns may include a slide lock or release that functions to lock a slide in its “back” position when a gun has expended all ammunition from a magazine. To prohibit a gun from locking its slide, a repeater 802 may be inserted into a slide 800 of a gun. The repeater 802 may disable a slide lock or slide release to prohibit the slide 800 from locking upon firing with an empty magazine (e.g., box magazine 102, 102′). Similarly, FIG. 9 depicts a repeater 902 comprising a fitted piece that may be secured to slide 900.

FIG. 10 presents a computing system according to an embodiment of the present invention. A system 1000 may include box magazine 1002, tracker interface 1004, tracker 1006, headset unit 1008, and virtual reality computing device 1010.

Power source 1024 may be connected to microcontroller 1030 and used by microcontroller 1030 to provide a voltage source to components within box magazine 1002 and tracker interface 1004 via pin connector 1022. As such, microcontroller 1030 may receive signals from closed electrical circuits connected to pin connector 1022 and transmit the signals to virtual reality computing device 1010 via wireless transmitter 1028. Virtual reality computing device 1010 may process or render the signals using processor(s) 1032 and transmit corresponding images to headset unit 1008 from wireless interface 1034.

Microcontroller 1030 may also provide power to sensors 1026 and wireless transmitter 1028 from power source 1024. Sensors 1026 can detect a position of tracker 1006 within the x, y and z coordinates of a space, as well as orientation including yaw, pitch and roll. From a user's perspective, a gun connected to tracker 1006 may be tracked when pointed up, down, left and right, tilted at an angle, or moved forward or backwards. Sensors 1026 may communicate where the gun is oriented to microcontroller 1030 which sends the data to virtual reality computing device 1010 for processing by processor(s) 1032 and renders corresponding images for transmission by wireless interface 1034 to headset unit 1008.

Headset unit 1008 may comprise a head mounted display, also including components similar to tracker 1006, that a user can place over the user's eyes. The headset unit 1008 may be configured to communication with the virtual reality computing device 1010 to provide display according to a virtual reality simulation program.

The processor(s) 1032 may comprise central processing units, auxiliary processors among several processors, and graphics processing units. Memory 1036 may include any one or combination of volatile memory elements (e.g., random access memory (RAM). Computer readable media storage 1038 may comprise non-volatile memory elements (e.g., read-only memory (ROM), hard drive, etc.). Wireless interface 1034 may comprise a network device operable to connect to a wireless computer network for facilitating communications and data transfer with tracker 1006 and headset unit 1008.

The virtual reality training software may comprise an audio/visual interactive interface that enables a trainee to interact with a three-dimensional first-person-view environment in training scenarios with tracker devices, such as a weapon including a virtual reality-enabled magazine assembly (e.g., comprising box magazine 1002, tracker interface 1004, and tracker 1006). Virtual reality computing device 1010 may receive signals or commands from tracker 1006 and headset unit 1008 to generate corresponding data (including audio and video data) for depiction in the virtual reality environment.

FIG. 11 presents an exemplary options menu of a virtual reality training software according to an embodiment of the present invention. The illustrated menu screen includes an “Options” 1102 that may be selected to adjust features. FIGS. 12 and 13 present an exemplary options interface according to an embodiment of the present invention. The “Options” 1102 may allow a user to configure settings for proximity rings, controls, and instructor audio.

Proximity rings may be configured for visually rendering different distances around a trainee that are visible in the headset unit. According to one embodiment, different actions may be prescribed for each proximity ring. That is, appropriate course of action may be determined based on a subject's distance from the trainee. Each proximity ring may be presented in a given color and distance that may be selected by the user. A user may select preferred units and enter distances for up to three rings.

Controls may be selected for each hand, as illustrated in FIG. 13 , by clicking on dropdown menus. Object types may be selected to identify weapon(s) to be displayed and characterized by the virtual reality training software. Object types may include both lethal (e.g., gun) and non-lethal (e.g., electronic control) weapons. Control type may also be selected to identify controller devices used with the system. A user may select as a controller type either a weapon equipped with a magazine simulator as disclosed herein or a standard virtual reality controller.

The user may also selected a microphone device to be used to receive instructor audio. Instructor audio allows an instructor to speak into a microphone to play directly into a virtual reality headset unit while a trainee is wearing it during a training session. Volume of the instructor audio may also be selected by dragging a slider control. A “mute audio” may also be available to turn off this feature during scenario or review mode. While training is taking place, an instructor may be able to see what the trainee is looking at in the headset unit from a computer or secondary screen and speak to the trainee to provide instruction.

Referring back to FIG. 11 , a user may select “Tutorial” 1104 to open a virtual tutorial. The tutorial may generate instructions for a trainee to follow along with familiarizing the trainee in a virtual reality environment through a simulated firing range. FIG. 14 presents an exemplary firing range screen according to an embodiment of the present invention. On-screen instructions may appear and guide the trainee to unholster a weapon, fire the weapon, and reholster the weapon. FIG. 15 presents an exemplary score screen that may pop-up giving the trainee statistics on how they performed.

Once again referring to FIG. 11 , the menu screen also includes “Library” 1106 and “Scenarios” 1108 that may be selected to enter into a scenario library. FIG. 16 presents an exemplary scenario library screen according to an embodiment of the present invention. The scenario library may include a plurality of scenarios available for selection and execution by the virtual reality computing device. A scenario may comprise a programmed simulation containing a given situation, setting, characters, and actions. A user may filter scenarios by type, time of day, environment, and/or language on the scenario library screen.

FIG. 17 presents an exemplary rendering of a scenario according to an embodiment of the present invention. Scenarios can be designed to place trainees in realistic situations requiring split-second decision making. A scenario may also feature branching options 1708 where an instructor may have the ability to pick an outcome based on options in the bottom right hand corner of the screen. The branching options feature may display the amount of time the instructor has to decide which outcome the trainee will receive. The instructor may select the outcome of the scenario until there is no more time on the clock. When the time runs out an outcome may be locked in and no further changes can be made. Scenarios may automatically have a default option selected if none is chosen.

During execution of a scenario, the instructor may access a menu of options by, for example, clicking in the top left corner of the screen. The menu may include options for proximity rings, simulation boundaries, and objects/weapons highlights. Proximity rings, as illustrated in FIG. 17 , may be enabled and disabled for showing how far away the trainee is from different location points in the scenario. The proximity rings may be rendered to indicate distances from the trainee during a virtual reality scenario and in playback of the virtual reality scenario during a review mode.

For example, proximity rings 1702, 1704, and 1706 may be displayed to the trainee and recorded for review mode. Each of proximity rings 1702, 1704, and 1706 may be color coded and labeled with approximate radius distances away from the trainee. According to one embodiment, the proximity rings may be color coded based on distance safety. For example, proximity ring 1706 may be colored green to indicate a safe distance while proximity ring 1704 may be colored yellow to indicate a cautionary distance, proximity ring 1702 may be colored red to indicate a high-risk distance.

Simulation boundaries may indicate a “training area” where the virtual reality system is only able to track trainee activity. The simulation boundary may be based on a limitation of the physical environment where the virtual reality system is configured. Objects/weapons highlights may visually emphasize any weapons or objects in the scenario held by either the trainee or other people. Instructors may also have the capability to pause, resume, restart, or quit the scenario at any point.

FIG. 18 presents a flowchart of a method for generating proximity rings according to an embodiment of the present invention. A virtual reality scenario is executed by a virtual reality computing device, step 1802. The virtual reality computing device determines whether proximity rings enabled, step 1804. Proximity rings may be enabled at any point during the virtual reality scenario. Upon determining that proximity rings are enabled, the virtual reality computing device retrieve proximity ring distances, step 1806. The proximity ring distances may be retrieved from settings configured by a user including one or more rings and corresponding distances in a given unit of measure (e.g., feet, meters, etc.).

Proximity ring arrays are generated based on the proximity ring distances, step 1808. The proximity ring arrays may comprise data structures representative of the shape, size, and distances of the proximity rings. A tracker location is determined, step 1810. Tracker location may be a location of a magazine simulator including a virtual reality tracker that is determined by the virtual reality computing device. The tracker location may be used to approximate a location of a trainee to place the proximity rings. The proximity ring arrays are rendered based on the tracker location, step 1812.

The virtual reality computing device may monitor for movements of the tracker, step 1814. If the tracker has moved, the virtual reality computing device may return to step 1810 to determine the tracker location and update the rendering of the proximity ring arrays at step 1812. The method may further determine whether the proximity rings are disabled, step 1816. If proximity rings are not disabled, the virtual reality computing device may continue to monitor whether the tracker moved at step 1814. In the case that proximity rings are disabled, the virtual reality computing device proceeds to remove the proximity rings from rendering, step 1818. The virtual reality computing device returns to determine if proximity rings are enabled at step 1804.

The virtual reality computing device may generate a review mode including a playback of the virtual reality scenario, wherein the review mode allows observation of the trainee and movements of the trainee from a plurality of perspectives. FIG. 19 presents a flowchart of a method for playback of scenarios under review mode according to an embodiment of the present invention. A scenario of a trainee is recorded by the virtual reality computing device, step 1902. The recorded scenario may be stored to a database for retrieval during a review mode. The review mode may be used by instructors to go over and evaluate a trainee's performance during the scenario.

A selection of the scenario for review is received, step 1904. A given scenario may include predetermined vantage points based on parameters of the scenario, such as environment. For example, a scenario in a house may include vantage points from a plurality of rooms. Vantage points of the scenario are retrieved, step 1906. Playback of the scenario is started from a default vantage point, step 1908. The virtual reality computing device may determine if a vantage point has been changed based on a user selection, step 1910. The scenario will continue playback of the scenario from a current vantage point if there are no changes to the vantage point, step 1912. If the vantage point has been changed, the virtual reality computing device may continue playback from coordinates of a selected vantage point, step 1914.

At step 1916, the virtual reality computing system determines if playback of the scenario is restarted. If yes, playback of the scenario is started from the current vantage point, step 1918. Otherwise, the virtual reality computing device may proceed to determine whether to end playback, either by end of scenario or by user command, step 1920. If playback is determined to end, the playback of the scenario is ended, step 1922. Otherwise, the method continues to determine if vantage point has been changed at step 1910.

FIGS. 20 and 21 present exemplary screens of a scenario under review mode according to an embodiment of the present invention. Once a scenario is over, an instructor may be able to access a review mode of the scenario to review a trainee's performance utilizing a variety of overlay and control features. The review mode may provide a menu of options for selecting vantage point, proximity rings, simulation boundaries, objects/weapons highlights, instructor audio, pause/resume playback of scenario, restarting the scenario, and quit.

Vantage point may allow an instructor to review training scenarios from different angles. For example, FIG. 20 depicts a playback of a scenario from a “Living Room” vantage point while FIG. 21 depicts a playback of the scenario from a “Center Stage” vantage point. Other vantage points that may be viewed for the illustrated scenario include “Dining Room” and “Hallway.” Availability of vantage points may depend on the scenario environment. The instructor may also view the playback of the scenario from a perspective of the headset (e.g., what the trainee saw). This feature allows showing of multiple angles from which the instructor can play back a scene. Reviewing from different angles may allow an instructor to watch how the trainee reacted, where they were looking as the scene unfolded as well as many other things.

The virtual reality training software may further generate analytics data from training sessions. FIG. 22 presents an exemplary analytics screen according to an embodiment of the present invention. Data from the training sessions may be tracked, such as user location, headset view angle, weapon angle and firing, branching events, and state of simulation. The analytics may also capture particular frames and timestamps associated with certain events.
